James Gunn Is Reportedly Already Writing a Third ‘Superman’ Movie

James Gunn rarely seems to slow down. With ‘Man of Tomorrow’ set to reach theaters on July 9, 2027, the DC Studios co-CEO is already looking beyond it. Fans eager for the next ‘Superman’ movie now have plenty to chew on.

The DCU’s first big-screen outing gave Gunn a lot of momentum to work with. ‘Superman‘ grossed $618.7 million worldwide against a production budget of $225 million plus a worldwide marketing budget of $125 million. Its follow-up brings back David Corenswet as the Man of Steel and Nicholas Hoult as Lex Luthor, with Gunn writing and directing.

Now comes word that Gunn’s next DCU film is a third ‘Superman’ movie, and that he is already working on the script. The claim started with an industry insider, who said Gunn had begun writing the project. Gunn has since confirmed he is hard at work writing his next film even as ‘Man of Tomorrow’ heads toward theaters next summer.

Gunn has not publicly named the project, so for now the third film remains a report rather than an official announcement. It does fit a pattern, though. Gunn has long been known for staying several steps ahead of his own release calendar.

This is not the first time Gunn has hinted at a longer plan. He told The Hollywood Reporter at the ‘Peacemaker’ Season 2 premiere that he had already finished a very detailed treatment for the next story in what he calls the Superman Saga. That label suggests he sees these films as a connected run, rather than a handful of standalone sequels.

The sequel’s own plot is taking shape too. ‘Man of Tomorrow’ is reportedly built around an uneasy alliance between Superman and Luthor as they face the villain Brainiac, played by Lars Eidinger. Gunn first teased the film with art of Luthor in his comic-book Warsuit, a sign that the rivalry is far from over.

The push to plan ahead arrives at a delicate moment for the DCU. ‘Supergirl’ opened to $37.1 million domestically and $62.6 million worldwide. It later ended its theatrical run with $126 million, well below a production budget of roughly $180 million.

DC Studios co-CEO Peter Safran acknowledged that the film did not meet box office expectations. He also described it as one piece of a broader, long-term strategy that the studio remains confident in. Milly Alcock is still confirmed to return as Supergirl in ‘Man of Tomorrow’.

Warner Bros. Discovery CEO David Zaslav has also said Gunn is working 16 to 18 hours a day on the sequel. That kind of effort shows how much rides on the film, which one analysis called the real test of whether the DCU has a sustainable audience.

Details on a third film are scarce, and Gunn has not shared a title, a release window or a villain. That leaves plenty of room for speculation, especially with so much attention on how ‘Man of Tomorrow’ sets up what follows. Whether the third movie builds directly on Luthor’s alliance, or takes Superman in a very different direction, is anyone’s guess.

For now, the safest bet is that Gunn intends to keep Superman at the center of the DCU. If the report holds, a third ‘Superman’ movie would give fans a trilogy to look forward to, and a clear sign that the studio plans to stay the course.
